Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Error C4503 when compiling on UE 4.9

Hi all,

My project works fun on Unreal Engine 4.8. I using boost in my project and all work fun. But when I trying to transplant to UE 4.9, I got some compile error with boost:

 error C4503:     “boost_asio_handler_invoke_helpers::invoke”: : decorated name length exceeded, name was truncatedC:\Users\...\ThirdPart\boost_1_58_0\boost\asio\detail\bind_handler.hpp    126

and when using UE 4.8 this had never happened.

Furthermore, C4503 seems like only a warning by default,and I have never found that warning in 4.8 before.But in UE 4.9, it cause a compile error.

So I think maybe a compile flag has pass to VC like "we4503" and I don't know where to find this flag or how to fix this error.

Could someone help me? Thanks a lot!!!!!!

I have print the build command, it is

You can disable particular cl.exe warnings by adding an entry to WindowsPlatformCompilerSetup.h.
